Why Fixed-Wing VTOL
The best of both worlds — multirotor flexibility with fixed-wing range.
Three Types of Drone
Each architecture makes different trade-offs. VTOL combines the strengths of both.
| Type | Range | Efficiency | VTOL | Runway | Endurance |
|---|---|---|---|---|---|
| Multirotor | 5–15 km | Low | ✓ | ✗ | 20–40 min |
| Fixed-Wing | 50–200 km | High | ✗ | ✓ | 1–4 hrs |
| Fixed-Wing VTOLOurs | 50–130 km | High | ✓ | ✗ | 1–2 hrs |
The Multirotor Problem
Multirotors generate all their lift from motor thrust — fighting gravity with raw power every second of flight. This is inherently energy-expensive. A typical quadcopter draws 300–600 W just to hover, leaving minimal energy for forward travel.
The result: 20–40 minutes of flight time and 5–15 km of practical range. For short-range inspection or photography, that's fine. For delivery over meaningful distances, it's a dead end.
The Fixed-Wing Solution
A fixed wing generates lift from airflow — once at cruise speed, the wing carries the aircraft's weight for free. The motor only needs to overcome drag, which at efficient cruise speeds is a fraction of the aircraft's weight.
The Stork cruises at 80–110 W — roughly a quarter of what a similarly-sized multirotor would draw. That efficiency multiplier is the difference between 15 km range and 100+ km range on the same battery.
VTOL Advantages
Range & Efficiency
Fixed-wing flight uses lift generated by the wing — not brute-force thrust from rotors. At cruise, the Stork draws 80–110 W compared to 300+ W for a multirotor of similar weight. That's 3–4× the range per watt-hour.
No Runway Required
Traditional fixed-wing aircraft need a runway or launcher for takeoff and a belly-landing area or recovery net for landing. VTOL eliminates all of that — take off and land vertically from any flat surface, anywhere.
Operational Flexibility
Deliver to a rooftop, a field, a parking lot, or a backyard. VTOL means your landing zone is wherever you need it to be — no infrastructure, no ground crew, no runway maintenance.
Scalable Payload
The Stork carries 200–500 g depending on battery configuration — enough for medical supplies, small packages, sensors, and specialty cargo. Fixed-wing lift means payload comes at less endurance cost than with a multirotor.
Autonomous Operations
VTOL enables fully autonomous door-to-door delivery. The aircraft handles every phase — takeoff, cruise, landing — without human piloting. ArduPilot's waypoint system manages the entire mission profile.
Wind Tolerance
A 1,620 mm wing handles wind conditions that would ground a multirotor. The aerodynamic lift surfaces provide stability in gusts, and the higher cruise speed means less drift and more predictable arrival times.
